ATIWEVE'Y' Patented Aug. 3, 1943 Alwyn BortomSouth Orange, N J.,assignor to- AssociatedPatentees, Inc., Ampere, N. J., a corporation offNew Jersey Application November 29, 1941, SerialNo. 420,962 5 Claims.(01. 242414) The invention hereindisclosed relatesto stock reels and theobjects of the invention primarily are to provide a reelconstructiononwhich the roll of stock may be readily engaged'and quicklyand easily centered and to "accomplish this in a simple, compact, sturdydesign of relatively few parts and low cost. Other desirable objects andthe manner of attainment will appear as the specification proceeds.

The drawing accompanying and forming part of the specificationillustrates certain practical commercial embodiments of the invention.The structure however may be modified and changed in various ways allWithin the true intent and broad scope of the invention ashereinatter-defined and claimed. l

Fig; 1 is a broken part sectional View of a stock reel embodyingfeatures of the invention.

Fig. 2 is a broken and partsec'tional frontpview of the reel. 7 r i Fig.3 is a fragmentary and part sectional detail View of, a power drivenembodiment of the invention. i a

As shown in Fig; l, thereel consists in the main of a series of stocksupporting arms 1, projecting ir-omplates or brackets 8, slidably guidedat 3; over the radially projecting spoke elements it, of the hub H.

Hub l l is shown journaled on a stud or spindle l2, carried by thesupport it, on the upper end of the stand :4, and controlled as tofreedom of rotation by the brake bushing I5, sli-dingly keyed hand nutll.

taking up the end thrust occasionedby the brake."

Radial adjustment or the con; supporting arms is efiected in'the'illustration by a c-a'mdisc or such points as will 1o cate' :thecoil supportsall at the same radial distance from-the center, eventhough the rolls necessarily areengaged with cam surfaces of unequaldistances from the center. At'present'it is preferred topintherolls onthe backs- 0f the pl-ates in thedifferent rel-atively rath'al positionsnecessary to locate the plates at equal distances from the center, butit is contemplated that the rolls may have adjustable mountingsgas inradially slotted portions on the backsof the-plates, thus to enablecomplete interchangepf the coil supports with the adjustments necessaryto properly locate the individual cam rolls,

Fig. llshows how the SCYOHCSJIII can be a relatively thin disc of anecessary thickness only sufficientto carry the cam groove, thus to takeup but small space'at the inner'end of thehub. This view also shows howthe thrust bearing i8 may be sunk in" the outer face of the scroll disc.i r

It desired, facings of brake-lining material or thelike, may1 beprovided between the opposite ends of the hub and the brake element atthe frontand the scroll cam at the back.

The brake element l5;is keyed at 23; orotherwise non-rotatably confinedon the stud, so as to brake the rotation of the reel to-a desired extentandthe cam plate, fric'tionally engaged as it is by the end of the reelhub and-backed up by'the thrust bearing I 8, is in effect frictionallycoupled to the" reel hub. The' itch of the scroll cam may be so low thatthe coil supporting arms will hold of themselvesin the positionstowhichthey have been adjusted, In any event however, the reel may befaced in the direction, whether for unwinding'or Winding on purposes,such that with any slippage at the friction clutch or coupling at 2resulting from the fdrag of the cam disc on the reel, such movement willbe'in the right direction to expand and tighten the arms in the coil ofsupported stock.

A holdingfpinris indicated at 25, Fig. 1, mounted in the spindlesupporting bracket, adapted to .beadvanced into one of the seats 23,"finthe back of the scroll cam for holding the latter,

when desired, for armadjusting or other purposes. This pin may haveasorew mounting as indicated at 21, or otherwise be set in the slipsport, so that while normally retracted, it may be readilygadvanced intoholding engagement with the camplate. This. holding: pin isdesir: ablefor securing the scroll pl-ate'and the reel fricticnally coupled theretoover extended periods as when placing or removing a heavy coil of stockin respect to the supporting arms and for holdirig'thecam while the reelbody is turned one way orthe other for expanding or contracting of theradially projecting coil confining flanges 28, of the arm carriers 8.

To facilitate the placing of the coils on and the removal of coils fromthe supporting arms,

the outer coil confining and retaining members 29, are preferablyremovably mounted as by equipping them with springpressed hand levers3B, pivoted at 3!, and having the eccentric or cam-shaped end. faces 32,engageable with the flattened outer sides 33, of the arms both toreleasably lock the retainers in place and to hold them against rotationon the arms. The locking on the hand levers 30, are faced so as to slidefreely inwardly over the coil supporting arms but to interlock andresist outward movement, the springs assisting in this holding actionbut yielding easily to spring pressure applied for releasing the holdingengagement.

What isclaimed is:

l. A reel of the character disclosed, Comprising in combination, asupporting spindle, a reel hub and ascroll cam rotatably'mounted on saidspindie in relatively rotatable relation and coil carryarms connectedwith and radially adjustable eccentric portions are faced to bind andsecure H The reelis of especially simple and compact design and isreadily assembled by simply slipping the scroll plate and the hub overthe spindle, then engaging the arm carriers over the spokes and backingthe hub up against the scroll plate to enter the rolls, in their properpositions in the cam groove, after which it isonly necessary to mountand tension the brake element,

which thereupon becomes a retainer for the whole structure, inadditionto its functions as a brake and as a means for maintaining thefrictional coupling between the reel hub and cam plate.

The invention is applicable to either free or motor driven reels. Anexample of the latter type is illustrated inFig. 3 and which differsfrom the form previously described, particularly in that a drive pulley0r equivalent drive means 36, is fixed to and carried by the inner endof the hub; I l and the scroll cam i9, is rotatablymounted on the hubinstead of directly on the spindle, between the innerface of the driveelement 36,

and a flange 31, on the hub. This mounting enables relative rotation ofhub and scroll cam, such as necessary to effect expansion andcontractive movements of the reel arms. A clamp screw is indicated at38, for securing the cam plate in fixed relation on the reel when thatmay be desired, as afteian adjustment of the end of the hub, against theopposing face of the stud supporting bracket M.

The motor for operating the power driven form of reel may be mounteddirectly on the reel stand asindicated at 42, and be connected with thereeloperating element 35, as by belt drive indicated at 43, as in the-A.E. Borton Patent the radial spokes and coil carrying arms and.

in respect to said hub, said coil carrying arms being connected withsaid scroll cam, whereby said arms will be shifted radially inwardly oroutwardly in respect to saidhub upon relative rotary adjustment of saidhub and scroll cam, said scroll cam being rotatably supported at theinner end of said reel hub, a thrust bearing at the back of said scrollcam in position to take endwise thrust on said reel hub against saidscroll cam and adjustable brake means for applying endwise pressureagainst the outer end of said reel hub and for thereby effectingfrictional coupling between saidhub and scroll cam.

2. A reel of the character disclosed, comprising in combination, asupporting spindle, a station.- ary support for said spindle, a reel huband scroll cam rotatably mounted on said spindle in relatively rotatablerelation and coil carrying arms connected with and radially adjustablein respect to said hub, said coil carrying arms being connected withsaid scroll cam, whereby said arms will be shifted radially inwardly oroutwardly in respect to said hub upon relative rotary adjustment of saidhub and scroll cam, said scroll cam being located at the inner end ofsaid hub adjacent said stationary support and a holding member on saidstationary support projectible therefrom into engagement with saidscroll cam for securing the same in non-rotatable relation.
